It's obvious that in a system _______ every decision is made on the basis of tradition alone,it may be difficult to achieve progress.
A.that B.when C.where D.which
但是不太清楚是怎么分析来的.

A

这是定语从句,(如果没记错的话),where是修饰system的,意思是在一个怎样的system里,这句话的意思就是,很显然,在一个只依据传统做决定的系统里,要想取得进步就可能会变得很困难

where后跟的是一个状语从句,'every decision is made on the basis of tradi..."这是一个完整的句子了,需要修饰的只能是状语,连接状语从句的只能是where,或者when,在这个句子中,表示的是一个环境(系统),所以用where.
例如:I forget where I put it.It is the place where we first met.
